Estimating Mine Water Quality. A Case Study: Borșa – Toroioaga Mine

Abstract

The entire mining activity produces, due to its specificity, multiple and varied negative effects on the
environment, exemplified by the impurity of surface and groundwater flowing waters, but also by the
hydrodynamic imbalance of groundwater. This work is conducted in the Borsa Basin, from Maramureş
Mountains, and includes areas located in the integral protection area, located in direct impact with the
Ciusla River. Through the studies and research carried out in this paper, it was aimed to highlight the risk
of pollution caused by mine water leaks, though quantification of pH, conductivity, and turbidity of mine
waters from 6 collecting points. Following the surveys, the affected environmental factors, the condition
and the decrease of the performance of the pollution installations were highlighted, which led to the
depreciation of the way of operation and their performance.
